A Republican-led amendment to the National Defense Authorization Act (NDAA) seeks to prohibit the development of a U.S. central bank digital currency (CBDC), citing privacy and surveillance concerns. Introduced by Rep. Keith Self, the amendment prevents the Federal Reserve from creating or implementing CBDCs, except for open, permissionless digital dollars that ensure cash-like privacy protections. This move addresses conservative concerns about potential government overreach in financial systems. The NDAA is poised for passage amid ongoing bipartisan negotiations.
